I've recently acquired the Al Murray '67 Brabham BT21-5, which was fully restored by Huffaker Race Engineering in 2016. I'm curious if anyone could provide expertise on how to properly refresh the Wobbly Wheels. I'm assuming they are magnesium? Is it as simple as media blast and paint? Or do they require special attention due to the fact they are magnesium? Additionally, the shoulder on one of the lug nut mounting perches is somewhat broken off. Is this a repairable situation? See attached photos.
Thank you
